METALLIC PIVOTET SASH WINDUVJ.

Specification of Letters Patent. Patentgd R5313 11 1313 Application filed May 31, 1911.

Serial No. 630,481.

To all whom it may concern.

Be it known that 1, JOHN 1. Born, a citizen of the United States, and resident of St. Louis, Missouri, have invented certain new and useful Improvements in Metallic livmed-Sash Windows, of which the following is a specification containing a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in metallic pivoted sash windows and has for its object to construct the jamhs and stiles each of a single piece of sheet metal with integral interlocking tongues and flanges above and below the pivotal connection between the sash and the frame, the meeting faces of the stiles and jambs being seamless to obviate dust and tire spaces as well as to construct the stiles and jambs with the least possible amount of material.

\Vitln the above purposes in View my invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in the claims and illustrated by the accompanying drawings, in which- Figure 1 is a perspective of the central portion of one of the stiles; Fig. 2 is a perspective of the central portion of one of the janibs; Fig. 3 is an enlarged, sectional plan of one of the stiles and one of the jambs taken on a line beneath the pivotal connection between the sashand the jamb; and Fig. 4; is a view similar to Fig. 3 taken on a line above the pivotal connection.

Referring by numerals to the accompanying drawings: 1 designatesthe body of the jamh. v

2 designates the central portion of the jamb which stands in a plane laterally re moved from the body portion.

3 designates a sheet metallic memherwh'ich connects the ends of the jamh proper 1 to form a substantially rectangular hollow jamb.

The central portion 2 HbOVErlZllB pivotal connection has an integral tongue l which is a continuation of the face of the"central portion 2 and extends over the body portion 1 to form a channel 5. Beneath the pivotal connection the central portion 2 has an integralhookshaped flange 6 which forms a channel 7 standing in a plane laterally removed from the channel or groove The tongue 4 and the flange (3, it is to be observed, are formed out of the material of the central portion 2, there being a transverse cut 8 which permits of the formation of the tongue 4 and the flange 6. For the reason that the flange (5 takes up more material than the tongue 4-, or at least. the projecting portion of the tongue 1, the extra material of the tongue at is placed to the rear or inside of the jalnb, as clearly shown in Fig. 3. In this manner the entire face of the central portion 2 of the jainb is formed seamless so that when the sash is titted thereagainst there are no dust cracks or fire spaces.

9 designates the body portion of one of the stiles, 10 the face of the stile which abuts the central portion 2 of the jamb.

11 designates a groove formed to receive the glass and 12 a channel-shaped member connecting-the ends of the material forming the stile.

The face 10 and the body portion 9 together with the portions forming the groove 11 are constructed of a single piece of sheet metal. 1

13 designates a out which is formed in the. stile at a point adjacent the pivotal connec tion, the material of the stile beneath the cut 13 isbent to form a tongue let which projects beyond the body portion 9. The material of the stile above the cut 13 is shaped to form a flange 15. The tongue lit is arranged for interlocking with the flange 6 of the jamb and the flange 15 is arranged for interlocking with the tongue 4 of the jamb.

16 designates a plate WlllChlS secured to the body portion 1 of the jamb and is pr videdwith a journal bearing '16. l I 18 designates a plate which is secured to the body portion 9 of the stile and carries a journal 19, the journal 19 being fitted in the bearing 17 so that the window may be tilted as required to open or close the same. I am aware that windows have been constructed having tongues and flanges which interlock to make dustand flame tight. connections betw far as I am advised, the tongues and the. flanges were" constructed of separate pieces andsecured to either the stile or jamb. Inother instances, where the tongues and een the stile and jamo but. so

flanges were formed integral with the stiles 3 ile and jarnh in thetaees 3 10;

thereof which aluitted. 'lliese not only tux-med tltlnt or [lame span-w hut were unsightly.
